Watmore is said to be one of the brightest prospects at the Stadium of Light, and has already made an impression this season by scoring twice from six first team appearances this season.
Defoe thinks the 21-year-old could be a useful player from the bench late on in games, telling the Sunderland Echo: “To have someone like Duncan who can come on and help you win the game, is a great weapon to have.
“He reminds me a bit of Andros Townsend, who is so direct and, every time he gets the ball, will just drive forwards.
“During the course of the season, he is someone who can come on and help us win games.”
Watmore has certainly shown signs of promise during his appearances this season and that he can be problematic for opposition defenders.
But Sunderland fans will be hoping he is a tad more successful than Townsend, who, if reports from the likes of the Daily Mirror anything are to go by, may have reached the end of the road in terms of his career at White Hart Lane because of a disagreement with a physio.
Watmore certainly has a lot of promise about him and has so many years of development left ahead of him. If he's handled in the right way, then the Black Cats may have a real talent on their hands.
